L 239/42 EN Official Journal of the European Union 19.9.2017 Subsidiarity: The principle of subsidiarity is key. Member States have the primary responsibility for the response in case of large-scale cybersecurity incidents or crises affecting them. The Commission, the European External Action Service and other EU institutions, offices, agencies and bodies have however an important role. This role is clearly set out in the IPCR arrangements but also stems from Union law or simply from the fact that cybersecurity incidents and crises may impact all sections of economic activity within the single market, the security and international relations of the Union, as well as the institutions themselves. Complementarity: The Blueprint takes fully into account existing crisis management mechanisms at EU level, namely the Integrated Political Crisis Response (IPCR) arrangements, ARGUS, and the EEAS Crisis Response Mechanism, integrates therein the new NIS Directive structures and mechanisms, namely the CSIRTs Network, as well as the relevant agencies and bodies namely the European Union Agency for Network and Information Security (ENISA), the European Cybercrime Centre at Europol (Europol/EC3), the EU Intelligence Analysis Centre (INTCEN), EU Military Staff Intelligence Directorate (EUMS INT) and Situation Room (Sitroom) in INTCEN, working together as SIAC (the Single Intelligence Analysis Capacity); the EU Hybrid Fusion Cell (based in INTCEN); and the Computer Emergency Response Team for the EU Institutions, Bodies and Agencies (CERT-EU). In doing so, the Blueprint should also ensure that their interaction and cooperation achieves maximum complementarity and minimum overlap. Confidentiality of information: All information exchanges in the context of the Blueprint must comply with applicable rules on security (1), on the protection of personal data and the Traffic Light Protocol (2). For the exchange of classified information, regardless of the classification scheme applied, available accredited tools shall be used (3). As regards the processing of personal data, it will respect the applicable EU rules, in particular the General Data Protection Regulation (4), the ePrivacy Directive (5) as well as the Regulation (6) ‘on the protection of individuals with regard to the processing of personal data by the Union institutions, bodies, offices and agencies and on the free movement of such data’. Core objectives Cooperation under the Blueprint follows the three-level approach mentioned above — political, operational and technical. At each level, cooperation may include exchanging information as well as joint actions, and aims to achieve the following core objectives. — Enable an effective response. Response may take many forms, ranging from identifying technical measures which may entail two or more entities jointly investigating the technical causes of the incident (e.g. malware analysis) or identifying ways that organisations may assess whether they have been affected (e.g. indicators of compromise), to operational decisions on applying such technical measures and, at the political level, deciding to trigger other instruments such as the EU Diplomatic Response to Malicious Cyber Activities (‘Cyber Diplomacy Toolbox’) or the EU operational protocol for countering hybrid threats depending on the incident. — Share situational awareness. A sufficiently good understanding of events as they unfold by all relevant stakeholders on all three levels (technical, operational, political) is essential for a coordinated response. Situational awareness may include technological elements about the causes as well as the impact and origin of the incident. As cybersecurity incidents may affect a wide variety of sectors (finance, energy, transport, healthcare, etc.), it is imperative that the appropriate information, in the suitable format, reaches all relevant stakeholders in a timely manner.
